All things Physicsy

8/24 – 8/28/15 (Pkt 1: Intro to Kinematics, Vectors)

Posted on August 30, 2015 by daskey

THIS COMING WEEK IN THE 807 : (my best guess as of 8/30)

Mon (8/31) — In Class: Our first Joke Monday; Our first slide show; Our first Book of the Week, discuss graphing 1D Kinematics

Tues (9/1) — In Class: More 1D Kinematics, Introduce the Metric Game (Hand Out sheet 1.3)

Wed (9/2) — In Class: More Metric Game, Introduce Unit Analysis (Hand out Sheet 1.4)

Thur (9/3) — In Class: Continue with 1D kinematics, Metrics, Unit Analysis; Pregame warm ups Evening: DESTROY THE NORTHERN MANGY PACK!!

Fri (9/4) — In Class: FBF, HO Part 1 of Take Home Test 1

THIS WEEKS SLIDE SHOW OF LAST WEEK:

( I will add captions before Monday morning. )

: Germany knows how to make a water park. This is an old blimp storage building.

: Since there is no ultimate spot on earth that is not moving.

: Turns out there is not a spot or a substance in the universe that can act as an ultimate reference substance. NO AETHER!!

: Michaelson and Morely

: THey were at Case Western University in Cleveland, Ohio. You should consider going there.

: Their interferometer.

: A drawing of their experiment.

: . . .

: Collin . . .

: A very bad drawing of the Milky Way and the super massive black hole (currently inactive?) at the center with a very approximate location of our solar system.

: We talked about this some. Just something that came up in discussion.

: Andromeda woul;d take up about 5 moon diameters in our night sky if we could see it’s light as it truly is. We just see a blurry dot from the Super Massive Active black hole in its middle. .

: KFC^2

: Our first walk on the glorious West Lawn

: Plotting our walk.

: . . .

: It’s important to know your limits. In Physics, numbers actually mean something. In other words they represent something you experience everyday. We walk at about 1 m/s and the fastest runner sprints at about 10 m/s.

: reminds me of my youth. I had a couple of these wigwams in our backyard.

: Sig Figs will be a topic for later. For now, just round your numbers to three digits.

: . . .

: . . .

: . . .

: . . .

: Coefficients are mathematical. They have no units.

: Constants DO have units. G is an example of a constant that we will talk about later.

: In algebra its the slope intercept equation. In physics it’s the opening kinematics equation.

: Trial 3, 4, and 4B also goes on the graph on the front of 1.1

: We didn’t actually go out to the west lawn, but you are supposed to graph this scenario. It must be a piecewise function. function.

: The opening page of each packet is going to be about you. I will ask three questions. You can take the whole page to answer them any way you want.

: The airline pilot says “nope”.

: 1.1.7

: 1.1.7

: Good idea to put the date at the top of your notes for that day. DO NOT start a new page or you will run out of pages about March 1st.

: 1.1.7 explained

: 1.1.7 explained

: 1.1.7 explained

: 1.1.7 explained

: position and distance are scalars. Displacement is a vector.

: Displacement is distance PLUS direction.

: Velocity is speed PLUS direction

: Scalars are numbers. Vectors are arrows.

: . . .

: In vector world 3 + 4 = 5. That is just one possibility .

: . . .

: . . .

: . . .

: . . .

: position is a scalar because there is no direction.

: Well, I did, but it is the Facebook section below.

: Our beloved three dimensions that we live in. Can anyone come up with an axis that is perpendicular to the other three? If you do . . .. congrats! you’ve just discovered the 4th dimension. Wait . . . maybe the fourth dimension requires you to curve space itself into an infinitely small space . . . kind of like what a black hole does! Just a thought.

: The Cantina will open this week or next week. Leaning towards next week because of all these regulations about healthy food.

: An example of a decently healthy breakfast you will be able to buy when the cantina opens up. That is a low fat ham, egg, and cheese inside an English wheat muffin.

: Here come the extra stamps.

: I will always post the links to the readings and videos on my website AND on Facebook.

: This may be the best video of the week. I liked it so much I shared it with my friends on facebook.

: Moonchild made a poster of Scalars and Vectors. SOme of the stuff on the poster won’t be covered until second semester.

: Brian posted this and I learned some new cool stuff.

: Tara helped my pet theory out with mini black holes as a window to the 4th dimension created in the LHC.

: Elizabeth showed vectors and scalars with Angry Birds.

: I added some family members to the group.

: Zach provided this extremely detailed tour of the control room of the LHC. I keep finding myself going back to this tour. It calms my nerves somehow.

: Emma posted a lot of cool stuff, but you can’t get much cooler than Dark Energy.

: Here is the vector map of wind velocities. This is from 2007.

: I THINK Tara was the first to post this one. The Chernobyl thing blew me away.

: We have talked about this one.

: Amber gets a stamp for simply being the first to ask about an actual homework problem. I’m not saying that everyone will get a stamp for asking homework questions, but she WAS the first guys.

: Oliver posted this annimation two minutes after I talked about it. That has to get some kind of recognition. I also showed it in class which means he gets even more stamps.

: Not really for a stamp or anything, but the cat taking over Emma’s physics notebook was too funny not to post.

: This is faucet is over engineered.

I WILL ADD CAPTIONS AND MORE PICS LATER TODAY
